Running a Retina Macbook Pro 15inch from last year. 8 Gigs of RAM. Dedicated Graphics. Decent computer basically.
Loading places, especially with terrain, is really annoying. Everything loads in extremely tiny chunks around my player.
Example, with my player circled: http://i.imgur.com/4AWPoNG.jpg
Some more information, I’ve tried this with another Mac in the house that has 16Gigs of RAM. All software is up to date and our internet should be more than enough strong at almost 20Mbps.
